Title: Strip Mounted Semiconductor Device
IPC: H01L23/495
Filed: 1968-09-13
Abstract: 1,181,336. Semi-conductor devices. GENERAL MOTORS CORP. 13 Sept., 1968 [29 Nov., 1967], No. 43613/68. Heading H1K. The invention relates to the provision of electrodes for and the encapsulation of semiconductor devices. In the embodiment shown each transistor die 46 is bonded via its collector to a once flat strip 10 of ductile metal. The strip is given rigidity in the mounting area by canted portions 34, 36. The emitter and base of the transistor are bonded by flexible wires 42, 44 to terminal strips 12<SP>1</SP>, 14<SP>1</SP> bent up from the strip. The transistor die (and perhaps the flexible wires) is given a first organic coating and is then encapsulated by transfer moulding or casting. The encapsulant 52 is kept from the lower face of the metal strip so that in use the collector may be directly bolted to a heat sink. During bonding, the encapsulant flows under the canted edges 34, 36 and under raised portions 48, 50 at the middle of the strip and when hardened is thus keyed to the strip. The terminal strips 12<SP>1</SP>, 14<SP>1</SP> are provided with enlarged ends 30, 32 to key them into the encapsulant. Each transistor is then severed from the strip by cutting out portion 54; the strips 12<SP>1</SP>, 14<SP>1</SP> may be straightened. The strips may mount, for example, 6-8 transistors which are processed simultaneously; single transistors would be made from a short metal blank, or transistors could be made sequentially on a very long strip. If a diode is to be mounted a strip may be produced with only one of the leads 12<SP>1</SP>, 14<SP>1</SP> or with both if the main strip serves only as a mount for a planar diode. Up to five electrodes (four of them forming pairs otherwise like 12<SP>1</SP>, 14<SP>1</SP>) may be used with, for example, a thyristor.

Abstract: 1490928 Stabilization of horizontal deflection circuits in television receivers LOEWE OPTA GmbH 27 Oct 1975 [19 Dec 1974] 44125/75 Heading H2F [Also in Division H4] A circuit to counteract effects of fluctuations on the format of the scanning raster of the tube of television receiving equipment, caused by variations in the electrical operating conditions of the horizontal deflection circuit, comprises. means to derive from each line scanning pulse a signal comprising a saw-tooth voltage component of constant peak amplitude and a unidirectional voltage component having a magnitude varying with a parameter of the respective scanning pulse, means. to compare the signal with a constant reference voltage to derive a control pulse when the amplitude of the signal exceeds the reference voltage, and means to regulate the energy received by the deflection circuit in dependence upon the duration of an interval between the initiation of the respective control pulse and the occurrence of a respective one of a series of reference pulses of constant periodicity. In Fig. 1 each scanning pulse, consisting of forward and flyback components 2, 3, is applied to a coupling capacitor 1 connected to components 5, 6, 7, 18, whereby the component 2 is passed by diode 6 to charge capacitor 7 until the component 3 biases the diode 5 to allow a part of the charge therein to pass back through resistor 18 into capacitor 1. This part is constant irrespective of the deviation from the normal scanning pulse a<SP>11</SP> of the scanning pulses a<SP>1</SP>, a<SP>111</SP>, Fig. 2(a), produced by variations of the operating voltage and/or the beam current, these variations causing the sawtooth waveform components of Fig. 2(b) (produced by the charge and discharge of capacitor 7) to be displaced by the unidirectional components U 0 1, U 0 <SP>111</SP> relative to the normal component U 0 <SP>11</SP>. The voltage across capacitor 7 is applied to a divider 8, 9, 10 for comparison with the voltage U Z  of a Zener diode 11, so that when the saw-tooth voltage exceeds U z  a transistor T 1  is turned on and when it falls below U z  transistor T 1  is turned off, Fig. 2(c). A differentiating stage 16, 17 causes a transistor T 2  to turn on at each leading edge of the "on" periods of transistor T 1 , the phase variation of these edges Fig. 2(c), producing a corresponding variation of the pulses applied to transistor T 2  relative to pulses P of constant frequency, Fig. 2(d). Switch-on of transistor T 2  fires a thyristor (not shown) in the horizontal deflection circuit, to cause part of the circuit current to flow back to the supply. The pulses P are those for triggering a thyristor in the line flyback circuit of the equipment.

Patent GB-446623-A (GB)
Abstract: 446,623. Retractive switches ; mechanical switches without quick action. ETABLISSEMENTS E. JAEGER, 2, Rue Baudin, Levallois-Perret, Seine, France. Oct. 8, 1935, Nos. 27796 and 27797. Convention dates, Oct. 8, 1934 and Nov. 8, 1934. [Class 38 (v)] [See also Group XXXVIII] A retractive switch for controlling a direction indicator of a motor vehicle comprises an operating spindle 2 slidable in a casing 1 and which carries at one end a knob 4 and at the other end a cylindrical insulating member 14 carrying contacts 18, 19 which extend round the upper half of the cylinder. The casing 1 carries three symmetrically arranged contact springs of which two 21, 22 are shown, and which normally engage a groove 20 in the member 14 to hold the switch in the off position. If the rod 2 is moved to the left or right and at the same time rotated one way or the other, contact 19 or 18 serves to connect contact 21 with one or other of the remaining contact springs to energize the corresponding left or right turning signal. The movement of the rod 2 to the right is without spring action so that the signal remains energized until the rod 2 is restored by hand. When, however, the rod 2 is moved to the left, a shoulder 2a engages a sleeve 5 formed with a rack 5a which engages a pinion 6 connected through ratchet-and-pawl mechanism with a fly train so that the rod 2 returns slowly due to a spring 7, and the signal is only made for a short time. The signalling system is shown in Fig. 7 and comprises a pair of semaphore arms 51, 52 operated by solenoids 51h, 52h each arm carrying a lamp which, in the lowered position of the arms projects from the casings and functions as a parking light. The direction switch 1 is associated with a two-position switch 53 having two pairs of fixed contacts 67, 68 and 69, 70 which in the operative position are bridged by conductors 64c, 65c. Contact 70 is connected to the ignition coil (not shown). When the two-position switch is in the operative position, if the direction switch 1 is moved to right or left the contact 0 engages either contact 23a or 22a and the corresponding solenoid and lamp are energized to give a direction signal. If the two-position switch is moved to the inoperative position (shown in broken lines), the ignition circuit is broken and movement of the switch 1 only energizes the corresponding lamp which serves as a parking light without the semaphore arm being raised. The twoposition switch comprises a casing 53, Fig. 8, on the base 66 of which are mounted the fixed contacts. The movable contacts are carried on an insulating member 60 rotatable by a cylinder lock 54 and key (not shown). The movable contacts comprise dumb-bell shaped members, the enlarged ends 64a, 65b of which are spring-pressed into engagement with the fixed contacts.

Abstract: 985, 400. Removal of radio-active materials from gases. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 22, 1961 [Dec. 30, 1960], No. 44757/60. Headings G6C and G6R. A process for extracting radio-active materials present as a vapour, or adsorbed on to, or absorbed by a suspended solid in a stream of carrier gas comprises flowing the stream along a flow path which includes a bed of extracting material and effecting an exchange reaction in said flow path between the radio-active form and a natural form of the same element. A suitable apparatus comprises a duct connected to a source of radio-active material, a bed of extractant material, e.g. carbon, in the duct and means for introducing the natural form of the element in a volatile form up-stream of the extractant material. Exchange occurs between the non-radio-active and the radio-active forms particularly on the suspended particles, thus presenting a greater amount of the free radio-active isotope for extraction by the extraction medium and thereby reducing the amount of radio-active material carried on the dust particles through the trap. This duct can be fitted on fume cupboards used for handling radio-isotopes, or on nuclear reactors using gaseous coolant so that the gases can be freed of radio-active contamination before being released to the atmosphere or returned to the coolant circuit. Elements having atomic numbers 38, 51, 52, 53, 55 and 56 are given as the possible isotopes and facilities for supplying each individual natural isotope in a vaporizable form may be fitted to the duct.
